Iron Man Suit paint protection

edited May 2016 in General
Hello all,
I'm currently 3D printing a Iron Man Mark 46 suit with PLA. I did a 2 part acrylic paint primer via HLVP sprayer and painted some of the parts via Enamel and Lacquer automotive spray paints. Would putting a 2 part urethane clear coat help strengthen and reduce scratches to the paint? Or is there a better option?
